domain of f(x)=log_{1/2}(x^2-2x-15)+7

domain

f (x) = lo g_{\frac{1}{2}} (x^{2} - 2 x - 15) + 7

x < - 3 or x > 5

Interval Notation

(- \infty, - 3) \cup (5, \infty)

Solution steps

Find positive values for logs:

x < - 3 or x > 5

The function domain

x < - 3 or x > 5

f (x) = ln (x^{2} - 81)

\frac{x ^{2} + x - 30}{x ^{2} - 4 x - 5}

f (x) = x^{2} - 12 x

f (x) = \frac{x + 7}{x ^{2} + 14 x + 49}

f (x) = (ln (x))^{l n (x)}

What is the domain of f(x)=log_{1/2}(x^2-2x-15)+7 ?
The domain of f(x)=log_{1/2}(x^2-2x-15)+7 is x<-3\lor x>5
